Definition
VACHIB1MO (H64M) reports the month that children received their first Haemophilus influenzae type b vaccination. This information is only available for children born in the 3 to 5 years before the survey whose first Haemophilus influenzae type b vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACHIB1DAY (H64D) and VACHIB1YR (H64Y) report the day of the month and the year of the first Haemophilus influenzae type b vaccination, as recorded on a vaccination card shown to the interviewer.
According to the DHS Recode Manuals, the vaccination date may be coded as "Inconsistent" if the reported date is inconsistent with the date of birth, the date of interview, or the dates of other vaccinations.
To identify all young children who received the first Haemophilus influenzae type b vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACHIB1 (H64).
